Abstract: Изобретение относится к оборудованию для стирки тканей и позволяет исключить механическое воздействие на ткань при ее стирке, отжиме и сушке. В стиральной машине, содержащей бак для стирки, водяной и воздушный насосы с трубопроводами и систему управления, также установлены бак для отжима и сушки ткани и нагреватель. Бак для стирки делится на две части, верхняя часть представляет собой емкость с гофрированными стенками и полуцилиндрическим дном. Под гофрами на одной стороне емкости и полуцилиндрического дна выполнены узкие щели. Нижняя часть бака имеет наклонное дно и разделительную стенку. Бак для отжима и сушки также делится на две части, верхняя часть имеет полусферическое съемное дно с отверстиями, а нижняя часть представляет собой зауживающуюся вниз емкость с решетчатой поперечной перегородкой. Баки соединены между собой, с насосами и обогревателем трубопроводами. Щели полуцилиндрического дна верхней части бака для стирки соединены с нагнетающей магистралью водяного насоса, а щели слива, выполненные на стенке этой части бака, соединены трубопроводом с нижней частью бака отжима. Нагнетающая магистраль воздушного насоса соединена петлевым трубопроводом с отверстиями на полуцилиндрическом дне. Всасывающая магистраль воздушного насоса установлена под полусферическим съемным дном в нижней части бака отжима. Процесс стирки в большей степени осуществляется за счет струйного и кавитационного воздействия на ткань, а процесс отжима и сушки осуществляется за счет выдавливания и испарения воды из ткани горячим воздухом. Отсутствие в баках вращающихся конструктивных элементов существенно повышает надежность и долговечность стиральной машины. 1 ил.
